Abstract: BATHTUB             Abstract of the Disclosure The invention is concerned with a bathtub having a bottom wall, a pair of sidewalls and opposed first and second end walls integrally formed with the bottom wall, the second end wall being angularly inclined outwardly to define an abutment surface against which a person lying in the tub may rest, and water inlet means for filling the tub with a mixture of hot and cold water.  According to the invention, the water inlet means extends through one of the sidewalls and is adapted to discharge a flow of hot and cold water along the one sidewall in a direction towards the second end wall so as to impart to the water a circulatory movement as it fills the tub and to thereby uniformly mix the hot and cold water and provide a uniform water mixture having a substan-tially constant temperature.

Abstract: Abstract of the disclosure:       In the continuous application of impregnating liquors to a wet textile web, there is a risk of the liquor being diluted by the moisture carried over by the textile material from the pretreatment, which, when dyeing liquors are applied, would immediately become visible to the naked eye by there being unlevelness between the ends of the web.  There are also problems in respect of the levelness of the goods because of the non-uniform moisture content of the textile material which is a consequence of variable squeezing performance on the pad-mangle across the width of the web.       The novel process and device eliminate the prob-lems which hitherto went hand in hand with wet-on-wet application by partly or completely exchanging the mois-ture on the goods by sucking or pressing liquor through the goods and by circulating the liquor to be applied while maintaining its volume and concentration at a con-stant value.  The new technique makes it possible to dis-pense with the customary intermediate drying stage after the pretreatment.

Abstract: ABSTRACT OF THE DISCLOSURE      A watertight slide fastener stringer comprises a row of discrete coupling elements mounted on a support tape and an auxiliary tape along their folded edge portions, there being first and second contact portions contiguous to the respective folded edge portions and engageable with corresponding first and second contact portions, respectively, of a like companion stringer to effect watertightness between the two support tapes and also between the two auxiliary tapes.  Each coupling element has a neck extending centrally from a base, and a pair of flanged legs extending from opposite ends of the base in the same direction as the neck so as to hold the folded edge portions of the support and auxiliary tapes between one leg and the neck and between the latter and the other leg, respectively.  Each leg terminates in a flange disposed on the back surface of the respective contact portion.  With the watertight slide fastener in closed position, if lateral pulling forces, for example, are exerted on the opposed tapes, the opposed coupling elements roll or tilt so as to reduce the tightness between the opposed first contact portions.  At the same time this rolling causes the opposed second contact portions to be pressed against each other with increased tightness, thus maintaining efficient and reliable watertightness between the opposed companion stringers.

Abstract: Abstract of the Disclosure In a hydrofining process, the life of a catalyst composition comprising a support selected from the group comprising alumina, silica and silica-alumina and a promoter comprising at least one metal selected from Group VIB, Group VIIB, and Group VIII of the periodic table is improved by mixing a decomposable compound of molybdenum with the hydrocarbon-containing  feed  stream  prior  to  contacting  the hydrocarbon-containing feed stream with the catalyst composition.  The molybdenum in the decomposable compound is in valence state of zero. A sufficient quantity of the decomposable compound of molybdenum is added to the hydrocarbon-containing feed stream to result in a concentration of molybdenum in the range of about 1 to about 60 ppm.  The introduction of the  decomposable  compound of molybdenum may be commenced when the catalyst is new, partially deactivated or spent with a beneficial result occurring in each case.
